This article investigates the problem of resilient dynamic event-triggered control for networked unmanned surface vehicles (USVs) with external disturbance in the presence of transmission delay and aperiodic DoS attacks. First, a network-based USV control system model is constructed and converted into a state space. Second, a resilient dynamic event-triggered scheme is designed to save system communication resources under aperiodic DoS attacks. Third, to ensure the security of the networked USV control system and to block communication with unknown jamming signals, a time-delay switching system model based on resilient event-triggered mechanism under aperiodic DoS attack is established. Then, by combining the Lyapunov method and linear matrix inequalities (LMIs), the criterion for asymptotic stability analysis and controller synthesis conditions of the resulting switching system is derived. Approach efficiency is validated by numerical simulation.
